Is an open-source library being used for this? Or can you describe the methods you use? I worked on this and related problems around extracting features from paper PDFs, we could all learn from how you did it.

Generally, an About page is always appreciated for such web tools with minimal UX, particularly when it's rather automagical.

Looks like it's just calling the crossref API

You can look at the network requests to see what it's doing. It's querying the OpenCitations database followed by the DOI.org content negotiation endpoint, which 302's to Crossref (or whoever the relevant DOI registration agency is).
